This patch fixes using pre/post increment/decrement operators with Objective-C 2.0
dot-syntax. For example,
object.property++;
would not work before this patch, but now it does :-)
The patch includes testcases, and I updated an old testcase where the object.property++ syntax
was commented out as it wasn't working yet.
Ok to commit to trunk ?
Thanks

* c-typeck.c (build_unary_op): Use
objc_build_incr_expr_for_property_ref to build the pre/post
increment/decrement of an Objective-C property ref, and skip the
lvalue_or_else check in that case.
